Re: [tesseract-ocr] 2 min on 1 page TIFF using Fast trained data

Just for future reference: for AVX (and ...) support there is needed to rebuild only tesseract - it depends on compiler and HW. Of course it make sense to use the latest version of tesseract dependencies (because of security, bugfixes etc) , but they have (AFAIK) minimum effect on tesseract speed (
